ABSTRACT:
An open head drum (2) is provided with an improved seal for preventing the entrance of contaminating air during jarring transport of the drum. The conventional open head drum includes a hollow tubular drum body (4), an integrally attached circular end wall (12) closing one end of the hollow tubular drum body, and a lid seat (6) defined in the hollow tubular drum body adjacent the open end for receiving a removable drum lid (10). The removable drum lid is likewise conventional having an inner wall (16) for closing the open end of the hollow tubular drum body and an outer wall (18) for co-acting with the lid seat in sealed relationship for closing the hollow tubular drum body. The improved seal includes an endless sealing membrane (30) extending continuously around the lid seat and the removable drum lid. The endless sealing membrane has a first annular portion (38) attached to the lid seat, a second annular portion (40) attached to the removable drum lid, and a flexible annular portion (42) between the first and second annular portions. When separation of the removable lid from the seat occurs, the endless sealing membrane at the flexible annular portion prevent ingress of atmosphere interior of the drum. A process of installation of the seal is disclosed together with the seal as an article of manufacture.
